ABSTRACT:
A servomechanism is controlled to move at a rate below a critical limit by means of a feedback controller (10) which is responsive to the output of a rate measurement device (9). The feedback controller (10) has a non-linear response whose effect only becomes appreciable when the measured rates approach the critical limit. Operation within the critical limits ensures stable and accurate operation of the servomechanism.
